Sodium Nitrate
CAS 7631-99-4NaNO384.99 g/mol
Sodium Nitrate is a versatile compound used primarily as a fertilizer and in glass production. Known for its high nitrogen content, it efficiently supplies nitrogen to crops such as cotton and vegetables while being less acidifying than alternatives. This industrial-grade white crystalline or granular solid also excels as an oxidizing agent in glass and ceramics manufacturing, refining clarity and reducing inclusions. Additionally, sodium nitrate finds applications in explosives, thermal energy storage, and food preservation, making it a valued component across multiple industries in Kenya and East Africa.
Main applicationFertilizer — Supplies nitrogen efficiently

Frequently asked questions
What is the CAS number of Sodium Nitrate?
The CAS registry number for Sodium Nitrate is 7631-99-4. Its chemical formula is NaNO3, with a molecular weight of 84.99 g/mol. Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.
What are the other names for Sodium Nitrate?
Sodium Nitrate is also referred to as Chilean saltpeter and E251. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.
What grade of Sodium Nitrate is supplied?
Sodium Nitrate is supplied as Industrial grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.
What concentration is Sodium Nitrate supplied at?
Sodium Nitrate is supplied at a concentration of 60% NaNO3. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.
What is the purity of Sodium Nitrate?
The purity/assay figure recorded for Sodium Nitrate is 99%. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.
What does Sodium Nitrate look like?
Sodium Nitrate is described as white crystalline or granular solid. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.
What is Sodium Nitrate used for?
Common applications include fertilizer — Supplies nitrogen efficiently, glass production — Refines clarity and reduces inclusions, ceramics — Acts as a fluxing agent, explosives — Oxidizing component, thermal energy storage — Part of molten salt mixtures and food preservation — Curing and color fixing in meats. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.
Which industries use Sodium Nitrate?
Sodium Nitrate is supplied to the Agriculture & Agrochemicals and Oil, Gas & Energy sectors. These are the industries this product is listed against in our catalogue; if your application falls outside them, we can advise on suitability before you order.
What packaging is Sodium Nitrate available in?
Available in 50 LBS (22.68 KG) bags. Where a different pack size or bulk delivery is required, it is confirmed at quotation stage against availability rather than listed here as standard.
What is the HS code for Sodium Nitrate?
Sodium Nitrate is recorded against the EC number 231-554-3 and the HS customs code 2834.10.10. Quote this on customs and export paperwork; it is confirmed again on the commercial invoice for your specific consignment.
